Why do I receive Error 129 - Unable To Connect To Primary Domain Server Instance when I attempt to log into Yosemite Server Backup?

Yosemite Server Backup, version 8.5 and above



This error can be caused by several things, the most common of which is that the Master Server is not running. The Yosemite Server Backup Administrator or the Yosemite Server Backup Service or Agent must be running on the Master Server for client systems to access the Storage Management Domain.


This error can also be caused by one of the following issues:

  • The Hostname or IP address of the domain server was specified incorrectly during the logon process from the client machine.

  • The database configuration settings on the client machine are incorrect. The ytconfig.ini file, located in the config folder in the root directory of the Yosemite Server Backup install path should be set as shown below.

databaseServerAddress=<IP address of the master server>

  • A firewall is preventing communication with the Master Server. Yosemite Server Backup requires two way communication on port 3817.

  • Multiple Network Interface Cards (NIC) are present on one system. Yosemite Server Backup enumerates NICs at the hardware level, so if a NIC is disabled, this could be an issue. To correct this it is necessary to bind Yosemite Server Backup to a specific IP address. For instructions on binding Yosemite Server Backup to a specific IP address, refer to Solution #00004011.
